Oogonium develops into early oocyte in the ovary, and then the oocyte leaves the ovary for the coelomic fluid in the form of single cell or cell mass followed by the rapid separation of the group of oocytes into individual ones. Oocyte enters into the nephridium after its maturation. The rupture of germinal vesicle marks the oocyte maturation. Oocyte in the coelom does not have follicle membrane and vitelline membrane is formed and developed by the oocyte itself. Smaller oocyte (0μm in diameter) is round, and larger ones (≥60μm in diameter) is ovate. The short and long diameters of a morphologically mature oocyte are about 115—120μm and 140—145μm respectively, and the vitelline membrane is 7—9μm thick.

卵原细胞在卵巢中发育至早期卵母细胞时期单个或成团脱离卵巢入体腔液中，卵母细胞团细胞很快分离为单个细胞；卵母细胞在体腔液中发育成熟后进入肾管；生发泡破裂是卵母细胞成熟的标志；体腔中卵母细胞无滤泡膜，卵黄膜的形成与发育靠卵母细胞本身；卵径小于60μm的卵母细胞呈圆形，卵径大于60μm 的卵母细胞为卵圆形，形态上成熟的卵母细胞短径约115—120μm、长径约140—145μm、卵黄膜厚7—9μm。

In addition, using RT-PCR to detect expression of centrin homogene during Urechis unicinctus spermatid deferentiation and early embryonic development. The result revealed that (1) expression of HsCEN1 homogene is present during spermatid defferentiation including spermtid and sperm, but not in adult tissues including body wall tissue,intestinal mucous memberane cells and cell in coelom succus;(2) expression of HsCEN1 homogene is not present in unfertilized oocytes but present in that of released polar bodies after fertilization and parthenogenesis oocytes treated with A23187;(3) expression of HsCEN1 homogene is present during early embryonic development including two-cell stage,multicell stage,gastrula to trochophora.

我们还用RT-PCR方法检测了Centrin同源基因在单环刺螠精子分化过程和早期胚胎发育过程的表达，结果显示：在单环刺螠精子发生过程中的精细胞、精子团、精子中都有表达，而在成体的体壁组织、消化道组织、体腔球中则没有表达；在未受精卵中没有表达，而在受精后释放极体的受精卵和经A23187孤雌激活的卵中则有表达；在单环刺螠的早期发育过程——二细胞胚胎、多细胞胚胎、原肠胚、早期担轮幼虫——中都有表达。

CWhen the fusion protein was co-culture with nematode,the analysis of fluorescence microscope showed the digestive system and the coelom of nematode could be detected green fluorescence, and the fluorescence intensity was time-and protein concentration-dependent.

其三，融合蛋白喂食线虫发现蛋白进入其整个消化道及其原体腔，且与喂食时间与蛋白浓度呈正相关关系。

The PGCs of Varicorhinus macrolepis first appeared in the mesoderm of early gustrula and subsequently remained in the hypoblast of the embryonic region during late gustrula and neurula stage. At the stage of muscular effect they were found in the splanchnic mesoderm and the proceeded around the gut to the dorsal mestery during hatching stage.

结果表明：泰山螭霖鱼PGCs最早出现于原肠早期；原肠晚期和神经胚期靠近卵黄囊的内胚层；肌肉效应器迁移到脏壁中胚层的肾原基附近；临出膜期到达体腔壁，随后，沿肠系膜进入两侧的生殖嵴中。

Objective To compare the changes of the number of the blood cell and coagulatory functions in the intracavitary blood before the use of Autologous Blood Recovery System and after.Methods The RBC,Hct,Plt,PT,APTT,FIB,TT of the intracavitary blood were measured in thirty-two patients with acute closing intraabdominal and intrathoracic hemorrhage.

目的 比较自体血液回收机处理后胸/腹腔内积血血细胞量和凝血功能变化的特点方法 32例急性闭合性胸/腹腔内出血病人，分别检测自体血液回收机处理前后体腔内积血的红细胞数、红细胞压积、血小板、凝血酶原时间、部分凝血酶原时间、纤维蛋白原、凝血酶时间。

Metastasis: A process in which that the tumor cells invade into vessels or coeloms and are transferred through blood, lymphatic and coelomic paths to other parts of body where they implant and grow into a secondary tumor.

定义：肿瘤细胞浸润到淋巴管腔、血管腔或体腔随体液运行或经体腔种植被带到它处，停留继续生长形成与原发瘤类型相同的肿瘤。原发瘤，继发瘤
